Quite Dump Valve.. why??

    Hi Guys,

    Recently fitted a Baileys DV30 Recirc dump valve to me Leon Cupra Mk1 and found that its not aloud as i first thought. I wanted a sound that is noticable outside the car whilst driving and i don't seem to have this. I have fitted a cheap cone filter to my car which i understand helps. Any ideas on how to make this louder, will a better air filter work?

    Thank You,

    Lewis ;)

    Take off the bonnet lining, that might help if you haven't already.

    I used to run a DV30 and thought it sounded fine, its certainly no quiter then the 008 I've got on now.
    Get a big jetex cone, remove the bonnet lining and do the n249 bypass.

    Bonnet lining, N249 mod will also help. If it still isnt too loud, get a Forge SplitR

    don't get split r there wank , just get a open cone filter and decent cold air feed and even with oem bosch valve(which imo is the best all rounder) you will get a nice induction whoosh

    Larger tip for more air
    Pay good money for a good cone filter like the jetex or apexi filters, not cheap crap
    N249 bypass
    remap

    If that doesn't satisfy, sell for a subaru or escort turbo or other car with a massively loud chavvy dump sound

    I was going to do that n249 bypass but read to many posts saying there cars not running right since they have done it so gave it a miss.

    Its easy to reverse, for every car that it runs bad, you get 20+ that run spot on. Your car, your choice :shrug:
